# from every config file version, which is not practical. So, I decided to defer
# this until it is actually needed. Even then, it is probably sufficient to only
# keep the versions where there is such a dependency.

Done. The original '${CFGFILE}' has been saved as '${CFGFILE}.before-upgrade' .
Will now run through 'ct-ng olddefconfig' . The intermediate configuration ( after the upgrade script,
but before running 'ct-ng olddefconfig' ) has been saved as '${CFGFILE}.before-olddefconfig' .
